Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial vehicle tracking systems struggle to detect non-cooperative UAVs and other airborne vehicles, particularly in uncontrolled airspace, due to their lack of onboard transceivers, leading to potential collisions and visibility issues for operators.
Innovation Solution
A radar sub-system comprising marine radars affixed to static support members, combined with data processing and correlation techniques, to identify and track aerial vehicles, utilizing ADS-B and telemetry data to enhance detection and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If non-cooperative aerial vehicles operate without onboard transceivers, then device complexity is reduced, but detection capability deteriorates
Solution Approach 1:
The patent introduces a ground-based radar system as an intermediary detection device to track non-cooperative aerial vehicles. The radar subsystem with transceiver components detects and tracks vehicles that lack onboard transceivers, enabling surveillance without requiring the aerial vehicles to have complex communication equipment.
2Length of moving object
If aerial vehicles fly beyond line of sight, then operational range is extended, but operator awareness deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the ground-based radar system continuously tracks aerial vehicles and provides real-time position and status information back to operators. This feedback loop maintains operator situational awareness even when vehicles operate beyond visual line of sight, allowing extended range operations with full monitoring capability.
3Difficulty of detecting and measuring
If imaging processing technology is added to UAVs, then detection capability is improved, but response time deteriorates
Solution Approach 1:
The patent employs a ground-based radar system that performs preliminary detection and tracking of aerial vehicles before potential collision scenarios arise. By detecting vehicles early in their flight paths and continuously monitoring their positions, the system provides advance warning that enables timely collision avoidance maneuvers, eliminating the delayed response associated with onboard imaging systems.
